Difference Between Reactants and Products (With Table)

The whole world consists of various chemicals. These chemical elements are undergoing several modifications, and it is called a chemical reaction that these chemicals turn into another chemical material. A significant part of our everyday lives is chemical reactions. For example, the burning mechanism allows one to take advantage of the ease of driving a car.

Chemical reactions that generate electricity using automobiles, trucks, and transport vehicles, make this possible. Brew, wine, cheese, and yogurt are examples of these food and drink brands.

Reactants vs Products

The difference between reactants and products is that the starting agent for a chemical reaction is reactants. Products are the chemical species found after the reaction has been completed. Chemical reactions of different forms include acid-base reactions, redox reactions, and combustion reactions. Therefore, due to the kind of reaction, it involves the same reactant that often gives different products. The biggest distinction is that reactants are absorbed during the reaction, while compounds are produced from the reaction.

Substances present at the initiation of a reaction are reactants during the reaction. Reactants should be used. There are no reactants present at the end of the reaction, or fewer reactants may be present (if the reaction is partially completed). Substances such as catalysts and solvents may also occur when a reaction begins. During the reaction, however, certain compounds are not consumed and are not categorized as reactants.

During a reaction, the products became the latest compounds. They form through the reaction between reactants and have characteristics distinct from those of reactants. The substance formed following a reaction is measured according to the number of reactants used, reaction time, rate, etc. Products are all we are involved in after a reaction, but there are different ways of substance detection and cleaning.

What are Reactants?

Chemical reactants are chemicals that combine to form a new compound. Air, for instance, consists of chemicals such as hydrogen and oxygen. Salt, consisting of a mixture of chemical elements, sodium, and chloride, is another example. These singular elements interact to form new chemical compounds or undergo a chemical reaction. In addition to the chemical element, more complex substances, such as compounds, can also include reactants.

Baking soda consists of many components, including sodium, hydrogen, carbon, and oxygen, for instance. The reaction between sodium hydroxide and carbon dioxide is chemical. The synthesis of calcium, hydrogen, and oxygen is sodium hydroxide. Carbon dioxide is a carbon alloy of two oxygen molecules. When combined with these chemical reactants, sodium bicarbonate is formed, or what is known as backing soda.

Chemists write these reactions in a chemical equation in a distinct manner. Chemical equations are written to point an arrow to the final result of the chemical reaction. These calculations also provide the use of other reaction compounds. Catalysts, enzymes, temperature, and other factors which can influence chemical substance interaction are included.

What are Products?

As the name means, substances made of chemical reactants are chemical products. The chemical product is baked soda in the illustration described in the previous section. It is made of sodium and carbon dioxide consisting of chemical reactants. Another example is water which, as discussed in the previous paragraph, consists of the combination of hydrogen and oxygen molecules. The final result is normally more complex than reactants in chemical reactions involving the mixture of atomic particles.

On the opposite, there are fewer complex chemicals with chemical reactions involving the reduction of atomic particles. These reactions normally break the chemical bonds in originally present compounds. An enzymatic mechanism is a clear example of this process. 

Catalase is a bacterial particle-produced enzyme. In breaking down hydrogen peroxide into water and oxygen, the enzyme is essential. That is why hydrogen peroxide is used for wounds to create bubbles.

In the bacteria that contaminate wounded beds, the catalase enzyme is present. As a consequence, hydrogen peroxide has been broken down into the previously cited chemical components. 

Chemical components are normally positioned on the right side of the arrow in chemical equations. However, chemical reactions are more complex, and compounds can also become reactants. These chemical equations typically use two arrows, which show the reversibility of the chemical.

Main Differences Between Reactants and Products 

  1. During the whole reaction, reactants are ingested, whereas products in the reaction are not absorbed.
  2. Reactants are visible before a reaction, whereas after reaction, products are available. (After a reaction, often responding reactants may also exist.)
  3. Reactants may or may not occur in the solution mixture at the end of the reaction, whereas products are found in the solution blend at the end of the reaction.
  4. Reactants are called substances that react with each other, whereas products are the new substances created.
  5. Chemical reactants are the beginning material for a reaction of chemicals, whereas products are chemical reaction material produced.


A significant part of life is chemical reactions. This is the process by which atoms and other more complex particles are converted into compounds. Chemical reactions normally occur between chemicals known as chemical reactants. These chemical reactants are subject to modifications that produce a different material, known as the commodity.

Reactants are normally taken up and transformed into a new product after the chemical reaction. The materials, on the other hand, are endpoints of chemical reactions, and at the end of the phase, they are made. Reactants are usually located on the right side of the arrow of a chemical equation. On the left side of the equation, therefore, chemical products are put.
